KISS Rebreathers New Syntactic Foam Insulation
Afraid of the cold?
Diving a rebreather in cold water where temps are below 45°F/7°C to that of freezing can impose a very significant affect to the overall functionality of the unit’s scrubber.
Looking back of rebreather basics, CCR Divers know that carbon dioxide (CO2) is removed through a chemical reaction as it passes through the scrubber absorbent. This chemical reaction is exothermic in nature, meaning heat is generated as part of the chemical process. For unit’s scrubber to work at best (let along work at all) the core temperature of the sorb must remain relatively warm. Allowed to cool too much, the exothermic reaction-taking place in the absorbent is diminished, eventually rendered the absorbent’s ability to extract CO2 in affective.
